Fortran 77 package by Jiri Zahradnik for 2-D P-SV elastic second-order finite differences.

The "FInite DIfference SOLver/Cartesian Arbitrary Domain SOLver" is a program package for the solution of partial differential equations. 2- and 3-dimensional systems of elliptic (stationary) and parabolic (time-dependent) equations can be solved. The boundary conditions may be arbitrary. The solution method is the finite difference method. For the FIDISOL part the solution domain is restricted to be rectangular. For the CADSOL part the domain is body-oriented, i. e. logically rectangular. There are versions with an adaptive grid generation. For CADSOL dividing lines can be prescribed allowing the solution of different partial differential equations in different subdomains or allowing noncontinuous conditions inside the domain.
